Condair’s continuous process of reporting and reviewing of product feedback is integral to our corporate value of being a reliable manufacturer. As part of this process, we have identified an issue affecting some RH2+ Space Humidifiers.

On some RH2+ units, water and/or drips may accumulate at the outlet of the fan grille. The root cause of this issue is incorrect fan speed settings applied during manufacturing.

SOLUTION - ADJUSTING FAN SPEED SETTINGS
|
- Remove the front cover of the unit, the rubber steam and condensate hoses, and the blower module. (See Figure 2.)
-
Identify the original manufacturer of the blower fan installed in the unit. The manufacturer’s nameplate is located on the fan behind the plastic diffuser. The manufacturer will be one of Mechatronics, EBM PAPST or Delta. (See Table 1.)
- Locate the power supply behind the blower fan. (Refer to Figures 2 & 3.) Adjust the power supply board jumper settings based on fan model as shown in Figure 1.

-
In some cases the fan may have also been overtightened during assembly. Check for bends and cracks in the blower fan frame. If there are bends and cracks like shown in Figures 4 & 5, please reach out to warranty department at na.warranty@condair.com to request a free of charge replacement under spare parts number 2570908.
